CAR-COUPLING.

SPECIFICATION forming part of Letters PatentNo. 366,779, dated July 19,1887.

Application filed Api-i128, 1887.

To all whom, 'it may concern:

Be it known that I, JOHN KRAMER, a citizen ot `the United States, residing at Vest Perry township, in the county of Snyder and State of Pennsylvania, have invented certain new and useful Improvements in Oar- Couplings; and Ido declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to 1o which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. t

This invention relates to car-couplersand has for its object theproduction of novel means for automatically coupling and uncoupling the cars when run together, which will be more fully hereinafter set forth, claimed, and shown 2o in the annexed drawings, in which-- Figure lis a perspective view, parts broken away, of the approximate ends of two cars embodying myinvention; Fig. 2, a vertical section of one part of the coupler,taken through the throat of the draw-bar, Fig. 3, a view similar to Fig. 2 of the other part of the coupler.

The coupler is composed of two parts. One part is placed on the end of one car, and the other part is placed on the opposite end of the 3o car to be coupled thereto. The coupling-pin of one car is supported by holding devices in readiness to engage the link carried by the car to be coupled, and the other car (the one to be coupled) is provided with a trip-arm to release the holding devices when the two cars are run together for coupling them.

' The draw-bars are constructed alike, and are composed of a front plate, A, having a central opening, and wings a ou each side ofthe open- 40 ing,formed fromthe plate, the plates or bars c', bolted at their forward ends to the rear of the plate A and united at their rear ends, and the plates abolted or otherwise secured to the inner si des of the bars c. The draw-bar C has four standards or corner guideways, B,united thereto at their upper ends-by the cross-bars B', formed with or separated from and secured to the standards, which are united at their lower ends by the short side bars, Z, and the 5o transverse bolts b. The pin-carrier,composed of an'uppcr and lower crosshead,D and D,re spectively, and the corner-posts D uniting the plates,is guidcdin its movements by thelower cross-head working between the guideways B, and by the corner-posts passing through openings in the cross bars B and through openings in the lugs or cross-bars B2, secured to the draw-bar. rIhe ends ot' the corner-posts are threaded and extend through the cross-heads, and nuts d, mounted on the threaded ends and 6o located on each side of the cross-heads, hold them adjustably in position. The pin E is supported by the upper cross-head ofthe car rier,and is adapted to pass through coincident openings in the plates a and of the draw- 65 head. The carrier may be held down by gravity; but a spring is preferably interposed between it and the drawsbar, and is located between the lower cross-head and the under side of the draw-bar, and is mounted upon the 7o cornenpost. There may be one spring for each corner-post, if desired. The pincarrier is held elevated by the lever F, mounted upon the armf, the holdingbar G, and the arm H, provided with the stop 7l., which is adapted to 75 enter the openingg in the bar G. rlhe inner end of the lever curves and is adapted tobear upon the upper cross-head about centrally thereof.

The draw-bar C is provided with the shaft 8o I, journaled in bearings J, depending from each side thereof. One end of the shaft projects beyond the side of the car, and has the handlever Il keyed thereto, for lworking it in its bearings for moving the linlcclamp, which is com posed of the cross-head K and depending arms lc,united at their lower ends by the rod k, which is connected with the shaft I by the arm ,projected therefrom. The cross-head K is located within the throat of the draw-bar, 93 and is adapted to clamp the link between it and thelower side of thedraw-bar. The arms lt pass loosely through the lower side of the draw-bar, and have coil-springs k2 mounted thereon for holding the cross-head K down. 95

In practice the link L is inserted in the draw-bar O, and is passed under the cross headof the link-clamp, and is held in position by the coupling-'pin Z. The couplingpin E of the draw-bar C, held up by the lever 10o F and the bar G,; passes over the stop h. The cars are .now run together and the trip M ,ses cured to the oar or draw-bar C. Striking the loar G disen gages it from the stop 71 and the-pin and carrier, being free, fall,land the pin E engages the link and couples the ears.

Having thus described myinventiomwhat I claim, and desire to secure by Letters Patent,

l. The -combination, with two Aears and a link and a trip Carried by one of the cars, ofa coupling-pin carrier, the lever F, the holdingbar G, and the stop for holding-bar carried by the other car, substantially as described, and for the purpose specified.

2. rIhe combination, with the draw-bar and the guide-standards, of the eouplingpin carrer composed of the corner-posts and the upper and lower cross-heads uniting the posts, substantially as set forth.

8. The combination, with the draw-bar and the cross-bars'loeated above and below the drawbar and secured thereto, and having apertures at eaeh end,of the coupling-pincarrier composed of the corner posts passed through the apertures in the cross-bars, and the upper and lowercross-heads,substant-ially as described.

4. The combination of the draw-bar, the

four gu'ideways secured at their upper ends to the draw-bar and connected at their lower ends by means substantially as shown, and the Coupling-pin carrier composed of corner-posts and the upper and lowery crossheads, the

spring, the lever F and arm f, holding-bar G,

cured tothe projected en d of the shaft, and

the arm extended from the rock shaft and connecting it with the link clamp, subst-antially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN KRAMER.
